Overview
The DA9130-XXRT2-A is an automotive-grade, high-efficiency single-channel step-down DC/DC converter with integrated switching FETs delivering up to 10A output current. It features a 2.5V to 5.5V input voltage range and supports output voltages from 0.3V to 1.9V via external resistor dividers for higher outputs. The device operates at a nominal switching frequency of 4MHz with ±1% static accuracy and ±5% dynamic accuracy. It includes I2C-compatible interface (FM+), programmable GPIOs, soft-start, and comprehensive protection features like undervoltage/overvoltage protection and 2-step over-temperature protection.
Feature Summary
- High-efficiency buck conversion exceeding 90% efficiency reduces thermal design challenges in high-current automotive applications.
- Fully integrated switching FETs eliminate the need for external FETs or Schottky diodes, optimizing BOM and footprint.
- Remote sensing capability ensures precise voltage regulation at the load point across various PCB routing scenarios.
- Dynamic Voltage Control (DVC) adapts supply voltage based on load conditions to improve efficiency during low-power states.
Applications
- Automotive navigation systems
- Infotainment systems
- Telematics units
- Advanced Driver Assistance Systems (ADAS)
- High-performance automotive processing systems
Procurement Notes
Verify the specific suffix configuration against the official Renesas datasheet to ensure correct pinout and functional parameters. Confirm AEC-Q100 Grade 2 qualification status for automotive reliability requirements. Check moisture sensitivity level (MSL) handling instructions prior to assembly. Ensure compatibility with I2C FM+ interface speeds and address settings defined in the control register map.
Selection Notes
Select this component for applications requiring a single high-current rail up to 10A with strict size constraints. Consider the 4MHz switching frequency for smaller passive component sizes compared to lower-frequency alternatives. Evaluate the need for remote sensing if long PCB traces exist between the regulator and the load. Verify that the input voltage range of 2.5V to 5.5V aligns with the system's power bus stability under all operating conditions.
Part Context
The DA9130-XXRT2-A belongs to the DA913X-A series of automotive-grade sub-PMICs from Renesas. It complements dual-channel variants like the DA9131-A and DA9132-A by offering a single-channel solution optimized for maximum current density. This series enables 'Exact-Fit' power solutions for complex automotive electronics, providing scalable options from 3A to 10A per channel within a consistent 24-pin FC-QFN package form factor.
Replacement Considerations
